Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Ryb, Ovna i Tel'ca, izmenyaya fazu ot 0,8+ do 0,95- i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Ryb. 15 noyabrya Luna (F= 0,84+) dostignet sozvezdiya Kita, a 16 noyabrya yarkii lunnyi disk (0,9+) eshe raz pereidet v sozvezdie Ryb. 17 noyabrya Luna vnov' zaglyanet v sozvezdie Kita, a zatem pereidet v sozvezdie Ovna pri faze 0,97+. Zdes' nochnoe svetilo proidet yuzhnee Urana (F= 0,98+) 18 noyabrya. V sozvezdie Tel'ca Luna voidet 19 noyabrya pri faze 1,0 i nastupit polnolunie, pri kotorom proizoidet chastnoe lunnoe zatmenie vidimoe na territorii nashei strany. 19 noyabrya polnaya Luna proidet yuzhnee Pleyad, a 20 noyabrya budet nahodit'sya severnee Giad i Al'debarana. Fazy Luny na dannoe vremya i na budushee.
